Application filed February 9, 1911. Serial No. 607,525.y

To all lwhom it may concern:

Be it known that I, SIGMUND FRnY, a subject of the King of Hungary,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inHose-Nozzles; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains t0 make and use the same.

This invention relates to improvements in hose nozzles.

One object of the invention is to provide a hose nozzle having animproved construction of spray regulating devices whereby a large orsmall spray or a solid stream may be thrown from the nozzle.

One object is to provide a nozzle having an improved discharge'mechanism whereby a line spray may be obtained with a high or lowpressure of water.

lVith the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts as will be'more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings: Figure 1 is a side view of my improvednozzle; Fig. 2 is a central vertical section of the same showing theparts in position for throwing a spray; Fig. 3 is a similar view showingthe parts in position for throwing a solid stream of water; Fig. 4 is across sectional view on the line M of Fig. 3; Fig. 5 is a similar viewon the line 5-5 of F ig. 3'; Fig. 6 is an inner end view of the largespray controlling valve or stopper of the nozzle; Fig. 7 is a detailview of the frustoconical shaped spring for holding the sleeve of thenozzle in its adjusted positions on the barrel ofthe nozzle; Fig. S is acentral ver` tical section of the nozzle showing a modified constructionand arrangement of the spray controlling valve; Fig. 9 is a similar viewshowing another modified form and arrangement of the valve; and Fig. 10is a cross sectional view on the line 10-10 of Fig. 9.v

Referring more particularly to the drawings, 1 denotes the barrel of myimproved nozzle, said barrel being in the form of a straight cylindricaltube of suitable length and having its inner end reduced to form anannular shoulder 2. On the inner end of the barrel is secured a threadedsocket 3 by means of which the nozzle is connected to the hose. Thesocket 3 has its inner end engaged with the shoulder 2 and the outer endof the barrel is upset against the adjacent chafed edge of the socket asshown thereby holding the socket in engagement with the end of thebarrel. In the socket is arranged a washer 4E.

In the outer side of the barrel 1 and at a suitable point between itsopposite ends is formed an annular groove or recess 5 in which isarranged a circular frusto-conical shaped sleeve holding spring 6.

Slidably mounted on the barrel 1 is a water controlling sleeve 7 on theouter end of which is formed an annular bead or corrugation 8 wherebysaid end of the sleeve is strengthened and the inner working parts ofthe nozzle protected. In the inner face of the sleeve 7 near its innerend is formed an annular groove 9 having an inclined rear wall 10. Whenthe sleeve 7 is drawn outwardly on the barrel 1 a suflicient extent tobring the groove 9 opposite the groove 5 the sleeve holding spring 6will spring into r engagement with the groove 10 thereby lim itingfurther outward movement of the sleeve 7 and thus preventing the samefrom being disengaged from the barrel. Vhen the sleeve 7 is pushedinwardly the cuter side of the'spring 6 has a snug frictional engagementwith the inner surface of the sleeve and thus will hold said sleeve inany desired position on the barrel, and at the same time will permit thesleeve to be adjusted inwardly or rearwardly within the limit of itsmovement on the barrel. When the sleeve 7 is drawn inwardly to the limitof its inward movement the inner end of the sleeve will come intoengagement with the outer end of the socket 3 and will form a flushcontact therewith as shown in Figs. 1 and 2 of the drawing.

rI he inner edge of the outer end of the barrel 1 is beveled or inclinedto form a valve seat 11 with which is adapted to be engaged la largeouter valve or stopper 12 said valve or stopper comprising a tubularbody portion, the outer face of the walls of which taper slightly vifromthe outer toward the inner end of the stopper as shown at 13. The innerend of the stopper is closed by an end plate 14 having formed therein anannular series of water discharge passages 15 and a centrally disposedguide passage 16. On the outer end of the stopper 12 is formed anenlarged head 17 having flared or beveled outer face which is adapted toengage the beveled edge or seat 1l formed in the outer end of the barrel1 whereby when the valve or stopper is drawn inwardly, the passage ofthe water between the same and the inner sides of the barrel 1 isregulated to produce a fine or coarse spray or may be entirely stopped.In the outer end of the valve or stopper 12 is formed an annular recessor depression 18.

Arranged in the outer stopper or valve 12 is an inner water deiiectingvalve or stopper 19, said valve being of tubular cylindrical form closedat its inner end and provided on its outer end with a flared head 20.The valve 19 is of less size than the inner diameter of the outer valve12 with which it is engaged whereby an annular space is formed betweenthe inner and outer valve through which the water passing through theopenings 15 in the end of the outer valve, will flow and upon reachingthe outer end of the valve 12 will strike the flared head 2O of theinner valve or stopper and will pass out between said flared head andthe recessed outer end of the valve 12 in the form of' a line spray. Thewater discharge space between the inner valve or stopper 19 and theouter valve 12 is always open and said discharge space always remainsthe same. By thus providing the water discharge space between the innerand outer valves the flow of water cannot be entirely stopped in thenozzle so that the hose will be relieved of the pressure of the waterwhich would occur if the flow of the same was entirely stopped in thenozzle.

'The valves or Stoppers 12 and 20 are held in position and the formeradjusted in the outer end of the barrel by means of a holding andadjusting bolt 21 which is inserted through the inner valve and theopening 16 in the end of the outer valve and has its threaded inner endengaged with a threaded aperture 22 formed in a spider or cross bar 23arranged in the inner end of the barrel and having its ends secured inopenings 24 formed therein. On the inner end of the bolt 21 is arrangeda nut 25. On the outer end of the bolt is formed a head 26 which engagesthe outer end of the valve 19 and around the part of the bolt in saidvalve and between the head of the bolt and the inner end of the valve isarranged a coiled spring 27 the pressure of which is exerted to hold thevalve 19 in engagement with the valve 12 and also hold the latter inengagement with its seat when in a closed posi tion. It will beunderstood that the spring 27 has a limited action on the valve 12 sothat while vthe bolt holds the inner valve 20 by means of its threadedconnection with the cross bar or spider 23 the pressure of the waterwill open the valve 12 to a greater or less extent and will pass betweenthe flared outer end thereof and the beveled end of the barrel in theform of a spray which will be coarser or finer according to the distancethe valve is opened.

In Fig. 8 of the drawings is shown a slightly modified arrangement ofthe valves, the latter being shown in this instance as comprising anouter valve 28 which is substantially the same as the valve 12 and isprovided with a closed inner end having formed therein water dischargepassages 29 and an enlarged outer end 30 having inclined or beveledwalls as shown. The inner valve 31 comprises a head 32 having a beveledinner end and is provided with an inwardly projecting sleeve or socket33 which projects into the outer end of the outer valve 28 as shown.Between the inner end of the sleeve 33 of the inner valve and the innerend of the outer valve 28 is arranged a coiled spring 34 which servesthe same purpose as the spring 27 shown in the first figures of thedrawings. rIhe valve 28 is provided with an attaching bolt 35 whichprojects through the valve and has its outer end secured in the innervalve 32 as shown. The inner end of the bolt 35 is secured in the innerend of the barrel 1 in the same manner as the bolt 21 and is similarlyarranged. 0n the outer end of the bolt 35 within the outer valve 28 andthe inner valve 32 is arranged a stop sleeve 36 the inner end of whichis adapted to be brought into engagementwith the inner end of the valve28 thereby limiting the inward movement of' the inner valve 32 which isadjusted by the bolt 35 thus preventing said inner valve from beingentirely closed.

In the form of the invention shown in Figs. 9 and 10 a single valve 37is provided.y said valve having a fiared or cone shaped outer end 38which is adapted to be moved into and out of engagement with the seatformed in the outer end of the barrel. The valve 37 is provided with asocket 39 having an interiorly threaded outer end with which isoperatively engaged a spring adjusting nut 40. Adapted to be insertedthrough a slot 41 in the nut 40 is a valve stem 42 having a cylindricalouter end 43 provided with a head 44. The inner end of the stem 42 isfiat and said flattened end projects through the slot 41 in the nut 40and projects a suitable distance beyond the inner end of the valve andinto the barrel 1 of the nozzle. In the inner end of the flat portion ofthe stem 42 is formed an eye 45 with which is engaged a transversefastening pin 46 the ends of' which are secured in the opposite sides ofthe barrel 1 as shown. On the cylindrical outer end of the valve stemand engaging the head 44 thereof is a washer 47 between which and thenut 40 is arranged a coiled spring 48 the pressure of which is regulatedby the nut 40, said nut being screwed inwardly or outwardly in thethreaded end of the valve by revolving the barrel l in one direction orthe other, said revolving movement of the barrel being imparted to thenut through the valve stem 42, which through its connection with thebarrel turns therewith. When the spring is in a released condition thepressure of the water in the barrel against the beveled inner portion ofthe head 38 of the valve will force the latter outwardly away from itsseat in the inner end of the barrel thus permitting the water to passout in the form of a spray which may be regulated by increasing ordecreasing the pressure of the spring 48 or may be entirely stopped byincreasing the pressure of the spring to such an extent that the samewill overcome the pressure of the water and thus prevent the latter fromopening the valve.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacriiicing any of the advantages of the invention as defined in theappended claims.
